Apparatus and method for discriminating biological tissue, surgical apparatus using the apparatus

Abstract

The present disclosure relates to an apparatus and method for discriminating biological tissue, and a surgical apparatus using the same, the biological tissue discriminating method being capable of exactly discriminating the biological tissue by measuring an impedance value per frequency, teaching the measured impedance value per frequency in a single classifier according to learning algorithms that are different from one another having the measured impedance value per frequency as an input variable to discriminate the biological tissue, and re-teaching the biological tissue discriminated from each single classifier in a meta classifier to finally discriminate the biological tissue.

Description

[0001]This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2015-0097370 filed on Jul. 8, 2015 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.FIELD[0002]The present disclosure relates to an apparatus and method for discriminating a biological tissue, and a surgical apparatus using the same, and more particularly, to an apparatus and method capable of discriminating what kind of biological tissue the biological tissue of a surgery area is, using an impedance value measured from the biological tissue of the surgery area and automatically adjusting an output energy of the surgical apparatus according to the discriminated biological tissue, and a surgical apparatus using the same.RELATED BACKGROUND ART[0003]With the recent development of surgical apparatuses, surgical apparatuses capable of performing coagulation and cutting of a surgery area at the same time using va...

Benefits of technology

[0008]Further, another purpose of the present disclosure is to provide a surgical apparatus capable of automatically adjusting outputs of various energy being used such as high frequency or ultrasonic wave signals and the like according to discriminated biological tissue, thereby reducing the duration of surgeries and preventing surgeries from going wrong.

[0025]The apparatus and method for discriminating biological tissue according to the present disclosure have an advantage of exactly discriminating the biological tissue having a nonlinear distribution by measuring the impedance values that is unique for each biological tissue according to frequency and then inputting the measured impedance values as a variable into a multi-classifier model, and a surgical apparatus using the same.

[0026]Further, there is also an advantage of further improving the exactness of discrimination than when using only the single classifier since the results of discrimination by the plurality of single classifiers are inputted into the meta classifier again and the biological tissue is finally discriminated.

[0027]Further, there is also an advantage of preventing erroneous surgeries and reducing the duration of the surgeries since coagulation and cutting may be conducted while automatically adjusting the energy output of high frequency waves and / or ultrasonic wave signals and the like being used according to the discriminated biological tissue.

Problems solved by technology

Here, in the case where an energy output that is weaker than a normal energy output is supplied to the tissue of a biological area being treated, there occurs a problem where the performance of cutting the tissue is degraded, making it impossible for the apparatus to operate properly, resulting in longer surgery hours.

On the contrary, in the case where an energy output that is stronger than a normal energy output is supplied instead, there occurs a problem where the energy is transferred to surrounding areas, thereby causing sparks, burns and unnecessary coagulation, etc.

These types of surgeries that depend on subjective thoughts of doctors have possibilities of causing trials and errors and prolonging the duration of surgeries due to unnecessary time spent.
